Usage
|
|
-----
|
|
|
|
The ``ssd1331_spi`` display platform allows you to use
|
|
SSD1331 (`datasheet <https://cdn-shop.adafruit.com/datasheets/SSD1331_1.2.pdf>`__,
|
|
`Adafruit <https://www.adafruit.com/product/684>`__)
|
|
displays with ESPHome. This component is for displays that are connected via the 4-Wire :ref:`SPI bus <spi>`.

|
|
|
|
Connect CLK (CK), MOSI (SI), CS (OC), DC, and RST (R) to pins on your ESP. For power, the Adafruit modules
|
|
require 5 volts connected to their ``+`` pin. Connect the GND or G pin to ground.
|
|
|
|
.. code-block:: yaml
|
|
|
|
# Example configuration entry
|
|
spi:
|
|
clk_pin: D5
|
|
mosi_pin: D7
|
|
|
|
display:
|
|
- platform: ssd1331_spi
|
|
reset_pin: D0
|
|
cs_pin: D8
|
|
dc_pin: D1
|
|
lambda: |-
|
|
it.print(0, 0, id(font), "Hello World!");
|
|
|
|
Configuration variables:
|
|
************************
|
|
|
|
- **dc_pin** (**Required**, :ref:`Pin Schema <config-pin_schema>`): The DC pin.
|
|
- **reset_pin** (*Optional*, :ref:`Pin Schema <config-pin_schema>`): The RESET pin.
|
|
- **cs_pin** (*Optional*, :ref:`Pin Schema <config-pin_schema>`): The pin on the ESP that that the CS line is connected to.
|
|
The CS line can be connected to GND if this is the only device on the SPI bus.
|
|
- **lambda** (*Optional*, :ref:`lambda <config-lambda>`): The lambda to use for rendering the content on the display.
|
|
See :ref:`display-engine` for more information.
|
|
- **update_interval** (*Optional*, :ref:`config-time`): The interval to re-draw the screen. Defaults to ``5s``.
|
|
- **pages** (*Optional*, list): Show pages instead of a single lambda. See :ref:`display-pages`.
|
|
- **id** (*Optional*, :ref:`config-id`): Manually specify the ID used for code generation.
|
|
|
|
Configuration examples
|
|
**********************
|
|
|
|
You may wish to add a ``color:`` section to your YAML configuration to make using colors easier; please see
|
|
:ref:`color <config-color>` for more detail on this optional configuration section.
|
|
|
|
.. code-block:: yaml
|
|
|
|
color:
|
|
- id: my_red
|
|
red: 100%
|
|
green: 3%
|
|
blue: 5%
|
|
|
|
...
|
|
|
|
display:
|
|
...
|
|
lambda: |-
|
|
it.rectangle(0, 0, it.get_width(), it.get_height(), id(my_red));
|
|
|
|
|
|
To bring in color images:
|
|
|
|
.. code-block:: yaml
|
|
|
|
image:
|
|
- file: "image.jpg"
|
|
id: my_image
|
|
resize: 96x64
|
|
type: RGB
|
|
|
|
...
|
|
|
|
display:
|
|
...
|
|
lambda: |-
|
|
it.image(0, 0, id(my_image));
|
